Kelly Osbourne enters a rehab

London (ANI): Popstar Kelly Osbourne has checked herself into a rehabilitation center, her mother Sharon has revealed. Although the reason behind Kelly's rehab visit has not been revealed, her mother said that it is the most awful thing she is going through.

"Yeah, Kelly's in rehab. What else can we say? She knew that it was the right thing to do at this point and we're proud that she did it. The family is all standing behind her. Kelly knew that she needed help and she's getting it," The Daily Express quoted Sharon, as telling RadarOnline.com.

"This is one of the absolute worst things that a parent can face, for their child to go through rehab. And not once, but twice," Sharon said. "However, we are all very glad Kelly's doing it," she added. Kelly's recent visit will be her second rehab stint, as she checked into a rehab in 2004 for drug-addiction.
